Comparison of Composite Materials Used
Material Performance Metrics
The selection of composite materials in architectural projects is anything but random - it’s a calculated choice tailored to meet specific performance needs. Each of the five projects highlights how different composites are used to achieve unique goals in modern construction.
WinSun’s fiberglass-reinforced concrete combines compressive strength with improved tensile properties. It brings corrosion resistance and cost savings to the table, though it doesn’t match the rigidity of carbon fiber. Mighty Buildings takes a different route with their UV-cured composite made from recycled glass. This material strikes a balance between sustainability and performance, offering consistent mechanical properties while speeding up production and keeping waste out of landfills. WASP’s clay and natural fiber composite focuses on harmony with the environment. Natural fibers like hemp deliver excellent thermal insulation, though they fall short in absolute strength compared to synthetic options. AIRLAB’s steel-bronze alloy joints, on the other hand, provide a significant strength-to-weight advantage - 10-15% higher than traditional steel alone.
Environmental Impact of Composite 3D Printing
The environmental footprint of these materials varies widely, but 3D printing in construction offers a game-changing potential to cut CO2 emissions by as much as 70%.
Among the projects, WASP’s Tecla stands out as the most eco-friendly. By using locally sourced clay and natural fibers, it minimizes transportation emissions and achieves a 24.6% lower global warming potential compared to traditional methods. Mighty Buildings follows a similarly sustainable path by incorporating recycled glass, which supports waste reduction by repurposing materials that would otherwise end up in landfills.
WinSun’s fiberglass-reinforced concrete presents a mixed environmental picture. While 3D printing reduces construction waste, cement production remains a significant concern, contributing roughly 7% of global CO2 emissions. However, the precision of 3D printing allows for more efficient cement use, potentially lessening its overall impact.
AIRLAB’s steel-bronze composite is the most energy-intensive option, as metal 3D printing can consume 50-100 times more energy than traditional methods. That said, the extended lifespan of these materials - lasting 2-4 times longer than conventional alternatives - may help offset the initial energy costs.
"Markforged printers also don't waste material and energy because they always produce the part that you designed - whereas with other 3D printers, there's a lot of worry involved."
– Ross Bonner, CTO at Transaera
In general, composite 3D printing significantly reduces waste, cutting construction waste by up to 95% and saving around 4.4 pounds of waste per square foot.

Future of Composite 3D Printing in Architecture
New Materials in Development
The evolution of composite materials is pushing the boundaries of what 3D printing can achieve in architecture. Researchers are now crafting advanced polymers with improved mechanical strength, chemical resistance, and thermal stability tailored for architectural use. These breakthroughs aim to make 3D-printed structures tougher and more adaptable to different environments.
Take, for instance, the work at the University of Virginia, where researchers introduced graphene-enhanced concrete in October 2024. This innovative cement-based composite combines graphene, limestone, and LC2, offering a greener alternative to traditional materials. Data from a Life Cycle Assessment shows that this material could lower greenhouse gas emissions by around 31% compared to standard printable concrete.
"The new composite material is a groundbreaking alternative for 3D-printed construction, as it demonstrates superior mechanical performance and produces fewer carbon emissions compared to conventional methods, thereby reducing its environmental footprint."
– Zhangfan Jiang, Postdoctoral Researcher, University of Virginia
Bio-based materials are also gaining traction. In February 2023, a team from DITF and Arburg developed a 3D printing process using cellulose continuous fibers reinforced with a cellulose matrix. This method operates at room temperature, making it energy-efficient. Crystalline cellulose, known for its high specific stiffness (67–137 GPa·cm³/g⁻¹), adds significant strength to these materials.
"The solution-based and energy-efficient manufacturing method developed by the research team can also be used in other composite materials manufacturing processes. It is particularly suitable for processing temperature-sensitive materials that are in high demand, such as natural or cellulose fibers."
